i don't do horny anymore. i reserve all of my energy for boozing or shopping on amazon.
HOWEVER, when i did do horny (in the last century) i noticed a correlation. either i'd spend nights too horny to sleep and spend the night jerking off and into the next day. or else i'd having trouble sleeping so i'd spend the night jerking off to relax and into the next day. either way i'd wind up with dark circles and a sore dick.
